There was no significant difference between breast cancer and control groups in the distributions of the genotypic or allelic frequencies as for the XRCC3 rs1799794 (p=0.5195 and 0.9545), rs45603942 (p=0.3478 and 0.1449), rs861530 (p=0.4567 and 0.5081), rs3212057 (p=1.0000 and 1.0000), rs1799796 (p=0.8487 and 0.7315) and rs28903081 (p=1.0000 and 1.0000), respectively.
We investigated three common polymorphisms (SNPs) in the XRCC3 gene (rs861539, rs1799794, and rs1799796) in 143 Saudi females suffering from breast cancer (median age = 51.4 years) and 145 age matched normal healthy controls.
The purpose of the present study was to examine whether five single nucleotide polymorphisms (SNPs) in Rad51 and Xrcc3 (rs1801320, rs1801321, rs1799796, rs861539 and rs1799794) exhibited an association with breast cancer susceptibility in a Belgian population of BC patients with a known or putative genetic predisposition.
